Product Description

Gcr15 SAE52100 Suj2 En31 100cr6 Bearing Tube 

Product Introduction
GB GCr15 bearing steel is GB standard Alloy Bearing steel, It belong to the high quality high carbon, alloy chromium,manganese  steel. GB GCr15 properties is a chromium,manganese alloy steel specification. GCr15 is equivalent to AISI 52100, DIN 100Cr6. Most applications can replace each others.

Alloy 52100 bearing quality / aircraft quality dual certified steel is a moderately deep hardening alloy having high resistance to wear, medium toughness, and low resistance to softening at high temperatures. It is an oil hardening high Carbon - Chromium alloy that develops high surface hardening.
52100 Premium Quality VAR is 52100 melted twice (vacuum arc remelted) and is used in various bearing applications for aircraft or other critical parts. It has excellent wear and abrasion resistant qualities and can also be used in place of tool steels. It has the same basic properties as 52100 but the VAR melting provides extreme cleanliness.

EN31 is a very high strength steel alloy which is hardened and tempered before supplying and has nickel, chromium, molybdenum making it high tensile steel strength, with good ductility and wear resistance. With relatively good impact properties at low temperatures, EN31 is also suitable for a variety of elevated temperature applications. EN31 round bars have good internal strength and high external strength, which makes it highly wear resistant. EN31 steel round bars offer good combination of ductility, strength and wear resistance. EN31 is a very high strength alloy engineering steel.
